I'm using a function called getPlayer which should return a player, but it says that the character is nil. My code is as follows, and the error where kill is marked, but probably with all other commands as well. If you can help, thanks.

root=script.Parent
player=game.Players.LocalPlayer

function getPlayer(name)
plyrlist = {}
found = 0
if string.lower(name) == "me" then return {player}

elseif string.lower(name) == "all" then return game.Players:GetPlayers()

elseif string.lower(name) == "others" then
plyrs = game.Players:getChildren()
for i = 1, #plyrs do
if plyrs[i]:IsA("Player") and plyrs[i] ~= player then
table.insert(plyrlist,plyrs[i])
end
end
return plyrlist

else
plyrs = game.Players:GetPlayers()
for i = 1, #plyrs do
if string.find(string.lower(plyrs[i].Name),string.lower(name)) == 1 then
char = {plyrs[i]}
found = found + 1
end
end
if found == 0 then return nil
elseif found == 1 then return char
elseif found > 1 then return nil
end
end
end

----------------------------------------------------------------------BAN
banned={}
root.Ban.Ban.MouseButton1Down:connect(function()
plr=root.Ban.Person

if getPlayer(plr.Text) then
plr2=getPlayer(plr.Text)
plr2:remove()
table.insert(banned, plr2)
end
end)


game.Players.PlayerAdded:connect(function(p)
for i, v in pairs(banned)do
if p.Name:lower() == v:lower() then
p:remove()
end
end
end)
----------------------------------------------------------------------CLEAN
root.Clean.Clean.MouseButton1Down:connect(function()
player.Character.Torso.Anchored=true
for i, v in pairs(Workspace:GetChildren())do
if game.Players:FindFirstChild(v.Name) == nil and not v:IsA("Message") and not v:IsA("Camera") then
v:remove()
end
end
a=root.Clean.Clean.Base:clone()
a.Parent=Workspace
a.CFrame = CFrame.new(0, 0, 0)
player.Character.Torso.Anchored=false
end)
----------------------------------------------------------------------INSERT
root.Insert.Insert.MouseButton1Down:connect(function()
asset=root.Insert.id
parent=root.Insert.parent

a=game:GetService("InsertService"):LoadAsset(asset.Text)
if Workspace:FindFirstChild(parent.Text) then
a.Parent=Workspace[parent.Text]
else
a.Parent=Workspace
end
a:MoveTo(player.Character.Head.Position - Vector3.new(10, 4, 10))
end)
----------------------------------------------------------------------KICK
root.Kick.Kick.MouseButton1Down:connect(function()
plr=root.Kick.Person

if getPlayer(plr.Text) then
plr2=getPlayer(plr.Text)
plr2:remove()
end
end)
----------------------------------------------------------------------KILL
root.Kill.Kill.MouseButton1Down:connect(function()
plr=root.Kill.Person

if getPlayer(plr.Text) then
plr2=getPlayer(plr.Text)
plr2.Character.Humanoid.Health=0
end
end)
----------------------------------------------------------------------LUA
root.Lua.Lua.MouseButton1Down:connect(function()
lua=root.Lua.code
Err=root.Parent.Err

worked, error = coroutine.resume(coroutine.create(function()
loadstring(lua.Text)()
end))
if not worked then
Err.Text=error
wait(5)
Err.Text="Output"
end
end)

GetPlayer returns a table, and from what I could see from the first command I looked at (I think it was ban... you should use DP for that :D), you were trying to index the return value as an instance. Is that the cause of the problem?

Oh nuts, it's a table? I knew that. >.> Thanks.

Also, I don't want to use DP with it because... Things could get out of hand in a script builder. :O
